iCircuit is the easiest way to design and experiment with circuits. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.
You use it as you would any CAD program: you add elements, connect them together, and set their properties. But iCircuit is unlike other CAD programs because it is always simulating. It's just like working with the real circuit. You do not stop to take a measurement or spend a lot of time configuring reports. Instead, you just play with the circuit as you normally would, with the power on!
There are over 30 elements you can use to build your circuits. The app has everything from simple resistors, to switches, to MOSFETS, to digital gates.
The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The scope can simultaneously track many signals over time and features a variety of automatic modes that make it easy for you to grasp the behavior of your circuit.
You can even export your circuits and PNGs, PDFs, and SVG files so that they are easy to include in reports or web sites. Scope data can even be exported for offline analysis.

Great App, Terrible support. Needs to be updated!
I’ve used this app many times to double check my theoretical problems on paper (for my college ELEG course), without having to physically build a circuit on a breadboard. The downside is that this app occasionally gives incorrect results. If you have a reading that doesn’t make sense, you can highlight the whole circuit and paste it. Then, delete the original and you will see the circuit gives different results. I’m not sure why this happens, but cut and pasting the circuit seems to “refresh” it.
In addition, for $9.99 I would expect to have a cross-compatible app that can be downloaded and synced across all devices for only one payment. If you want this app on both your iPhone and your MacBook, you’ll unfortunately have to fork out additional $$$. I’ve contacted the developer several times about this and have had NO reply. They have terrible support for their app.
NEEDS FULL SCREEN
Well…i think it's quite amazing that the DEVs haven't updated this app and integrated Lion's capability of displaying apps at full screen capacity…after all lets admit it, it's much nicer, and nicer's important to mac owners…that's a big reason why we purchase Macs…Style, beauty, functionality and portability. Not only it does allow you to fully take advantage of your display, but now with Mountain Lion and the ability to stream what's on your Mac's screen onto a bigger HDTV dramatically supports my theory. It does indeed increases your productivity to work in full screen mode i think... Allow for FULL SCREEN in next update please, and i'll give it a 5 stars with a simple "great"….because aside from that, this app is indeed great at what it does…only if it was capable of doing so on a bigger screen!
Good, but not great.
If you need somthing for basic circuit analysis (early level circuits courses), this is great. If you need something for quickly drawing basic circuits for publishing, this is also great for that. If you want to do some serious analysis, keep waiting, because this is very basic.
For my purposes, which is basically exporting .jpgs for use in publications, it works great. I bought it for this purpose, so I am not dissappointed. However, any time you attempt to paste something into the work space, such as a .jpg or .gif, it crashes and you lose all work. This happens EVERY SINGLE time. Once they fix this, it will serve my purposes 100% perfectly and I will rate it 5 stars.
